The vibration-absorbing sheet 11 is made of a rubber-based material, a plastic-based material, or a highly vibration-damping material such as hardness-adjusted chloroprene rubber. The air bag 12 is
A large number of press-fitted air bags 12 are combined into a sheet shape, or the like. Then, a plurality of layers of the vibration absorbing sheet 11 and the sheet-shaped air bag 12 are stacked to form the plate-shaped vibration absorbing material 1. Furthermore, as shown in FIG. 4, an integrated structure in which a large number of bubbles 13 are sealed within the vibration absorbing sheet 11 can also be adopted. When the vibration absorbing material 1 is to be built into the groove, a frame material 14 made of steel or the like is attached to the peripheral edge of the vibration absorbing material 1, as shown in FIG.
